OpenTracker+.


In the Overland Navigator setting utility, expand the “NMEA Interface (Optional) item. Select
the COM Port connected to the null modem cable from the OpenTracker+. Select 4800 as the
baud rate.
Note: Due to the nature of the ‘virtual’ COM Ports created by USB to Serial converters, the port
does not exist until the converter is connected. Make sure that the GPS cable and the cable
used to connect the OpenTracker+ to your computer are plugged in before attempting to
configure Overland Navigator.
Overland Navigator is now ready to use. Other vehicles or locations broadcasting APRS information will
be displayed on your map screen. Due to the type of NMEA data word provided by OpenTracker+, Live
Waypoints will not be displayed using APRS symbols. Live Waypoints will be shown as a round waypoint
marker labeled with the station’s ID.
